To investigate the changes in depositional environment around Gangneung Harbor, we analyzed the surface sediment textural parameters and topography data collected five times from February 2007 to February 2009. In the study area, sediments were mainly composed of sand and its sediment size became finer at offshore sites. During summer time, however, the sand grains became coarser than winter season near Namhangjin Beach, inside the harbor, and offshore areas. On the other hand, the grain size of Anmok Beach showed a gradual finer trend with time. Compared with the previous studies conducted before the completion of Gangneung Harbor construction, the mean grain size became finer on Anmok Beach, while it was coarser on Namhangjin Beach. The bathymetric changes observed over a 2-year period showed predominant erosion in the area of 5 to 10 m water depths and deposition in 2 to 5 m water depths. The shallower area less than 2 m water depths showed an alternating trend and yet slightly more dominant erosion process. The sediment textural parameters and the distribution of erosion and deposition have changed continuously. Results imply that such changes show long-term trends as well as seasonal variations in which the trend may have been formed after the completion of Gangneung Harbor construction.

This paper analyzed the color of harbor and fishing village for the better landscape. Accordingly the aim of this study is to find out the color-scape in harbor, such as regional color and present status are to analyze with elements of design. In beginning point of development, it is to take practicable data about color planning for marine tourism. Regarding the utility of these characteristics, hue, value, chroma can be checked and design of color-scape may be possible to work out future harbor environments. This study suggests that harbor of contemporary is to be environmental harmony and regional color control. The result of this research, it is carried out that the color-scape is checked by partnership of experts, official and regional person with "agreement of landscape" to provide reasonable criteria in color surroundings. An analysis of regional color-scape is expected to use for landscape improvement of fishing village and harbor.

It was analysed that spatial and temporal change patterns of COD, TN and TP were measured monthly from 2002 to 2005 in Jumunjin Harbour. Cenerally, concentration of upper layer higher than lower layer, concentration difference of COD, TN and TP on upper lower layer at inner zone in Jumunjin Harbour higher than sea area front of breakwater. Seasonal change width of COD concentration different, but seasonal change pattern of COD, $NH_{4}-N$ and TN clearly showed. Water quality improvement effect of seawater exchange facilities and sewage treatment plants is analysed quantitatively using averaged spatial and temporal data set. Change of COD small at 2003, concentration reduced about $34{\sim}47%$ at all zones on 2004 and 2005. TN was influenced largely effect of seawater exchange facilities. Concentration reduction at zone 1, 2, 3 estimated about $60{\sim}70%,\;40{\sim}60%,\;40%$, respectively. As a consequence, concentration reduction of COD and TN that is, effect of water quality improvement influenced seawater exchange facilities appeared not only at inner zone, also sea area front of breakwater and entrance of Jumunjin Harbour.
